INVENTORv FERRUCCW GU\DETT\ Patented `an. 175', 1.935 i UNITED .STATES Parisi? This invention .relates ato ,plumbing appliances .fand lmore particularlyrefers `toimprovernents .in sanitary attachments for water closets *and bidets of :the ltype wherea :nozzle bearing arm is brought from -an inoperative to'anioperative ,position for dire'ctinga jetvofnuid l'ag'ainst the bodyof the occupant of the vvseat :for 'cleansing purposes.

A .sanitary vWater fclose-tattachmentr of the :type to which this invention refers has been described vand claimed in` 'a ycopending,application entitled Flushing -'arrns'for sanitary water closet attachf ments, lSerial No. 516,858, (now -matured "into Patent No, 1;;872-278 issued August 1'6, v19821), .tiled by me as co-inventor vwithfGiuseppe 'Bontempi. n

The arrangementfdescribed in saidapplication comprises y -a supporting frame attached onto the rim of the b'oWlf'of the-watercloset'orbidetfby means oi a'clampi-ng-hook, a flushing -or `water delivery arm movable ffrom'an inoperativefposih .tion directly above theirim'of the bowl tto van operative position within the bowl, means for vdisplacing said arm Hbetween its two extreme positionsand for causing rotation of *same about its axis `while it-is so moved, and valve meansfffor admitting 4cleansing fluid ftofsaid arm after it has reacheditsfoperative position. l

'When said arm is i-n its.inoperativoposition=it remains fia-t above the rim of the bowl, and kwhen itis broughtto -i-ts .operativepositionthe nozzle provided at the end of said arm comes-to occupy .a position within the f bow-l -inA 4which its axis remains on a vertical longitudinal plane .passing through the center ofthe ybowland-is upwardly inclined .towards the rear yof 1thebowl. Water runder pressure .issuing-from 1fthe nozzle will `therefore be projected in an upwardly Ainclineddirection towards the` lrear ofthetbowl.

More particularly the direction 4off the lluid'jet issuing from the nozzle will besuch thatthe fluid under .pressure will strike directly against the body outlet ofthe occupant of-the sea-tin connection with which the cleansing operation` is to be performed. u H

The ushing .arm thus provided, WhenUini-ts Ainoperative position, 4has its free or `nozzle. end resting above the rimat-the-rear of thebowl, the outer end of said arm being Apivotally mounted -upon the f supporting frame ,at a y.point spaoedlaterally of the bowl, `located on vorinr close proximity vof a transversal yaxis ,passing through the'center of the bowl.` y

The translatory` orangular movement of the yiiushi-ng arm in ahorizontalgplane is effected by arm, striking a stop fduring the trislatory movement of the arm.

I have lf'ound .in `practice that the ariange- Land fth'erefoie it is desirable vthat the :flushing arm remain entirely fa'bove the rim `l-of 'the bowl and A.away'froin.the-"cavityof the bowl, yetwhen the arm extends'above'ltheirear 'ofthe bowl,.it1is still exposed'to 1 contamination )through carelessness of the user, and, fther'e'fore, further im provement in this direction is in order.

The position :of the .pivotal support of the 1 flushing arm, pointed out above, is suchthat the supporting frame )extends very lmaterially `from the side of the bowl.

In certain instances, this has provedto b'e a serious 'obstacle to the adoption of t'heimpr'vei ment because i'of lack .of suci'ent clearance vf space between theebowl fand: the Wall.

VI have falso fou-nd that fthe 'operation Vof the flushing arm' bymeans'foffaiplunger member imjposes l'severe stresses uponthe various 'parts of i Athe mecha-niemand also-entails various vcomplications of, design. The'fclampinghook attach-` ment advocated in :said application particularly has been -fou-nd WantingA vin-'th'e matter ofV 'sta- `bility and rigidity, '-loecause of the stresses liinposed @upon `lit by the considerable `downwardly directed force applied against the plunger ymember ata material #distance from the point 1 'of attachment A of the vdevice on'tof-the bowl.

Accordingly, the primary object `Vof this i-nventicn =isfto provide a sanitary attachment lof the :character specified adapted to be secured onto the bowl of a Water closet or bidet; inffa manner which will cause said lattachment to project but little in a `lateral direction so as not to create undue diicultes in ther matter .of space requirements.

.Anotherfobject isito provide in`a sanitary atv .tachment p of the character specied 'a .flushing or water delivery armr swan-ranged that `when f inoperative it rests above the rim and .-"away from thegcavity-ofthe bowl at the side -of the bowl, so as to occupy a position less likely to lbe `exposed 'to Ithe possible-effects vof carelessjness vor inadvertence.

A further object is to provide a device of the class specified where a ushing arm is caused to move from an inoperative position above the rim of the bowl to an operative position within the bowl, means of a simple and positive character for securing the device in position, said means being adapted for use in connection with practically all makes of bowls.

A still further object is to provide in a device of the class specified Where the flushing arm is caused to move, froml an inoperative position above the rim of the bowl to an operative position within the rim of the bowl, operating means of an improved and simpliiied Idesign whereby said arm can be caused to acquire a translatory and a turning movement through agsingle movement of the operating member, the operating member being rotatably mounted and being, therefore, smoother in action than an operating member of the plunger type.

Other objects and advantages of the present invention will more fully appear as the description proceeds and will be set forth andclaimed in the appended claims.

My invention is illustrated bygway of example in the accompanying drawings invwhich:

Fig. 6 is a'vertical section through line 6--6 of Fig. 5, .l

Fig. 7 is a vertical section through line 7-7 of Fig.

Fig. 8 is a detail view in elevation of the valve controlling member; and

Fig. 9 is a cross sectional' view thereof.

Referring to said drawings, 10 designates a toilet bowl of usual construction formed with a rim 11, surrounding the bowl cavity 12, and having a rearextension 13 carrying hinge bolts 14, 15, by means of which the seat 16 is attached to the bowl.v The lower surface 17 of the seat is usually provided with rubber spacing feet 18 resting upon the edge of the rim 11, causing a clearance 19 to` remain between the edge of the bowl and the lower surface of the seat.

The device illustrated comprises a supporting frame 20 upon which all the operating parts are Ymounted, said frame being surrounded by a shield 21 and a cover 22 and being connected by screws 23, 24, tothe downwardly extending leg of an L-shaped bracket 25 having a at horizontal abutting arm 26 inwardly extending from the device transversely of the axis of the bowl, as shown in Fig. 1.

Said arm 26 is provided with two openings 27, 28 through which can be inserted the stems of hinge bolts 14, 15,v in order to secure the device in position. The lowerendlof the downwardly extending arm 26 of bracket 25 is provided with an adjusting screw 25', as shown in Figs. 4 and 7,.said screw resting against the side of the seat attachment extension and positively supporting the device against .downward displacement. y

As Fig. 1 clearly shows, when the device is thus secured in position it occupies the recessed space 29 formed at the rear by extension 13 with the body of the bowl proper so that the body of the device does not project to an excessive extent laterally of a vertical plane tangent to the side of the rim of the bowl.

The ushing arm 30 extends inwardly in a direction inclined towards the front of the bowl from a pivotal attachment 31, and terminates with a curved portion 32, provided at the end with a nozzle 33, said curved portion remaining flat directly above the side portion 34 of the rim of the bowl when the flushing arm is in its inoperative position shown in Figs. 1, 2 and 5.

From said normal or inoperative position, the arm may be angularly displaced in a substantially horizontal plane about pivotal attachment 31 to the operative position shown at 30', 32' in Figs. 1, 2, where its nozzle will occupy the position 33', where it is upwardly and somewhat rearwardly directed along the longitudinal verf tical median plane of the bowl at a suitable distance beneath the plane of the seat 16, as shown 'in Fig. 2.

-jecting from the horizontal leg 37 of an elbow tubular piece 38, the vertical leg of which 39, is screwed onto the upper end of vertical pivotal member 31, as shown in Fig. 7.

When said pivotal member together with elbow member 38 is angularly displaced in a counterclockwise direction with respect to Fig. 5 about the axis of pivotal member 31, a slotted dog 40, integral with arm 30, is caused to engage a stationary pin 41, so that while the arm progresses towards the center of the bowl it is compelled to rotate about its axis in the direction shown by the arrow in Fig. 4. When the flushing arm is angularly displaced in the opposite direction, from its operative to its inopera- Ytive position, the opposite side of the slot 42 in slotted dog 40, will bear against pin 41 and will cause the arm to rotate in the opposite direction.

Vertical pivot 31 is rotatably mounted in a lug 43 upwardly projecting from body 20 and is provided with an axial opening 44, establishing communication between a passage 45 extending from a chamber 46 and elbow member 38. Said pivot v31 is retained in position in any suitable manner, for instance, by means of a nut 47.

Said pivot 31 also carries a plate 48 which is clamped between the bottom of part 39 of elbow member 38 and a nut 49. Said plate 48 constitutes 'the driven member of a Geneva type of control for causing the angular movement of pivot member 31 and elbow member 38, the driving member of said control being constituted by an arm 50 provided with a vertical stem 51, engageable at its upper end 52 by the hub 53 of an operating handle 54. Said stern is rotatably inserted through a bearing plate 55, which is attached by means of screws 56 onto a lug 57 vertically extending from the body 20.

The lower surface 58 of arm 50 is provided with a square recess within which is inserted the 'square upper end 59 of a vertical valve controlupstairs .fling/member 160,whichis:rotatablysmountedrand whichxextends 'within 'and beyond -chamber @46.

The lower end :of saidyalve :controlling :member is enlarged :to .formfa conicalfhead 61 restning 'against ia -seat 'providedv at Vthe bottom :of .iframe .120 :and the 'end surface of said :"coni'cal :head lis pressed iin position aand-wise `by -a vplug :By `virtue lof `this construction when/stem :51 4together with warm v50 .is .rotatedrby means of l-handle 54, iits -rotation :is "transmitted Yto valve Amember 60, as will Lbe understood. As stated, acts "as vthe driving memberof falGeneva 'control and, therefore, is provided lwith an `upfwardly projecting pin 63, Avengaging a .slot .64 `iorriie'd in '-jpla'te 48, and isfiurthermore provided with een lupwardly projecting segmental `member 365 adapted -to .engage 'and to register with a circular arc rportion 66' of plate 48 :and to :retain lsaid :plate 48 in position .afte'r pin 163 has caused a predetermined-angular imovement of l.plate 48. it will be seen that kif stem 51 together with :arm 50 `is :angul'arly` displaced .in a clockwise direction with Lresp'ect ito Fig. 5, `plate V48 together lwith pivot 31 and elbowmember 38, kwill ybe :displaced a 'certain 'angle in al counterclo'ckwise direction untilise'gmental member 65' en- `,gages `circular arc -`portion 66. When this position has `been reached Istem y5l and arm 50.can still continue to rotate in the same direction, but plate 48 will b'e securely restrained against further angular movementin either direction.

The rotation of `stern 51 lis effected against Athe action =of a spring 67, which will return all the parts to their normal vlposi-tionshown in Fig. 5, as soon as handle "54 is brought from the 'position shown in full lines in Fig. l to the posi- 'tion shown in dotted lines, shown at 54', and `during 'its movement the flushing arm is rst brought from the position shown vin full lines to fthe position `shown in dotted lines in the same ligure and then valves regulating the rsupply of cleansing liquid to chamber 46 are actuated `by 4valve con-trolling member 60 to-admit liquid to said chamber.

The device is `'shown equipped with two Yvalves .'68, z69, 'which are axially rmovable within-glands 70, '71, said "glands beingy connected respectively to sources of V'cold and khot water supply-by means of tubes 72, '73. Y y f lThe Astems of 'said valves project within chamber 46 and during the rotation of valve controlling -inember 60 .are acted upon to force said valves outwardly by radially extending cam-acting lugs 74, 75, with which valve controlling member 60 is provided. Said two lugs are preferably angularly displaced with respect to each other in relation to the axis of the valve controlling member, so as to operate the two valves in proper sequence.

Preferably said lugs are arranged so that during the movement of member 60, after the ilushing arm has been brought to operative position, lug '74 will iirst bear against valve 68, causing the same to admit cold water to chamber 46, and as member 60 continues to rotate lug 75 will force valve 69 outwardly causing hot water also to be admitted to chamber 46. If member 60 is further rotated in the same direction, lug 74 will pass beyond valve 68, allowing the same to close, while lug 75 will continue to bear against valve 69 so that hot Water only will be admitted to the chamber 46.

In thisvmanner by regulating the extent of the angular movement of handle 54 it becomes possibleito iregulate'zthe benipenatmfe "of fthe water admitted to the chamberfaandisuppliedtto the nozzle. 1

is thus .seen that by Vplacing the device tow'ards theirear :of .thefbowl 1.it v.becomes :possible f Itorcause the ".nushing arm :to 4extend frontwardly kfand to :rest lover the .side portion of .fthe rim-of the bowl. In ithis 'position'V the :arm :is :less f-likely 'to' be i-.inadvertently :contaminated 'than if the :arm were iplacedzover fthev rear portion of the s rim.
